This study aims to present a numerical and experimental transient characterisation for mono- or bi-layered ceramic samples and dental restorations under a controlled cooling process from high temperature (typically 900°C) to room temperature (25°C). The processes may undergo different cooling rates: namely rapid cooling, normal cooling and slow cooling. The cooling rate is not a constant during convection. Cooling rate dependencies of the temperature distribution about the glass transition temperature during cooling will be taken into account. The heat transfer coefficients used in this numerical simulation are derived from experimental data. The FEA results are correlated to experimental results and a good agreement is achieved. The transient material processing models showed a significant potential for development of optimal prosthetic devices
